Thanks for your consideration:
* I think it's fine to add a simple query right here in this .test file. I 
agree it does not make sense to add a dedicated test file.
* I think we should still add a test for the following reason. When we scan 
that file, the BE reads the file schema and resolves it against the table 
schema. There is no test that covers that the BE scanner reads and resolves a 
Parquet field annotated with ENUM correctly, so imo that coverage is missing. 
Even if it works today, someone may "fix" the Parquet scanner in the future and 
break this functionality.
